injury.
No load bearing . Do not use the pump to support other items of equipment that impose
unacceptable loads on the pump. Do not attempt to use this machine as a prop.
Lock trigger safety latch when not spraying . Spray gun is equipped with a built-in
trigger safety latch to guard against accidental trigger release. Rotate safety latch to
the locked position when not spraying.
Leaving unattended . Always turn off the pressure washer and relieve system pressure
before leaving the sprayer unattended.
Prompt Emergency Response
Seek medical aid for suspected injection injury . If injured by high-pressure fluid, no
matter how small the wound is, see a doctor at once. A typical injection injury may be
a small puncture wound that does not look serious. However, severe infection or
reaction can result if proper medical treatment is not administered immediately by a
doctor who is familiar with injection injuries.
Seek medical aid for suspected carbon monoxide poisoning . The running engine
gives off carbon monoxide, a poisonous gas that can kill you. If you start to feel sick,
dizzy, or weak while using the pressure washer, shut off the engine and get to fresh air
RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
Put on
personal
protective gear
WARNING :
Use personal protective gear to prevent:
- Eye and skin injection injury from high pressure spray
- Burns from hot water or steam
- Eye injury from flying debris
1. Wear waterproof, thermally insulated gloves, safety glasses with side and top
protection, face protection, and protective clothing when operating the
machine. If spraying pressure washer specific chemicals, wear a respirator
mask to avoid inhalation of vapors if directed on the chemical label.
2. Wear non-slip, protective footwear. Use of pressure washer can create
puddles and slippery surfaces. Wear footwear capable of maintaining a good
grip on wet surfaces.
Prime the
water supply Turn on water supply and squeeze the trigger.
CAUTION: Never run the pump without the water supply connected and
turned on. Operating the pressure washer without a sufficient incoming
flow of water will damage the pump.

Turn on the water supply. Make sure the water supply is steady and flowing
at a rate 20% over the rated flow of your pump. (See Step 1, "Connect Hoses,
Water Supply, and Nozzle").

Purge air from the water supply hose by squeezing the trigger until a steady
stream of water flows out of the nozzle at low pressure. (Air in the hoses can
cause damage to the pump, so always make sure all the air is out of the hoses
before starting the pressure washer engine.)

Make sure the water supply hose is not kinked. A kinked hose will provide
insufficient water supply to the pump and reduce its life. Make sure the hose
remains unkinked after moving the pressure washer.
